The Met’s Heilbrunn Timeline of Art History pairs essays and works of art with chronologies, telling the story of art and global culture through the Museum’s collection.
The habitat halls were an integral part of the expansion of the Museum (then the Los Angeles County Museum of History, Science, and Art) in the early 1920s. They provided visitors with a close-up view of the natural environments in which the animals were found. This was a particularly important aspect of the Museum's mission because, even then, many of the larger mammals were becoming rare due to human encroachment into their preferred habitats.
The Conservation Department employs 20 staff, including professionally qualified conservators and technicians who are responsible for the conservation and restoration of works in the collection. The Department is divided into five sections: Paintings, Objects, Textiles, Paper and Preventive Conservation. The Department is concerned with the treatment, display and storage of works in the collection. In addition, works of art in national and international exhibitions are prepared for travel. The conservator's job is to stabilise the object's condition and slow down the natural deterioration processes. This is done through a variety of treatments of varying complexity, and through preventive conservation measures. The conservation approach to each object will vary depending on factors such as its physical nature, its cultural significance and artistic intent. All treatments and scientific investigations are documented; all materials used in conservation treatments are tested for long-term stability and reversibility in the future.
